Plastic or paper? That’s a question grocery shoppers have answered for quite some time. But now, at least one national chain, Whole Foods, won’t be offering plastic bags any longer. Whole Foods claims the decision is earth-friendly, and popular with consumers, but according to a column by Jeff Stier of the American Council on Science and Health, the decision could have some unintended results in major cities – namely, more cockroaches. Stier notes that cockroaches like to live in creases in paper bags, and often chew into the paper to lay their eggs. Since cockroaches can also significantly increase asthma symptoms, this could make inner-city asthma problems even worse. So doing away with recyclable plastic bags may not be so light a decision, after all.
